Hi everyone, this is Neo.

Something happened in the SEO world recently that made everyone’s jaw drop. Jon Goodey, an SEO expert, ran what you can only call a “crazy” experiment: he published a piece of content hallucinated by AI about a “March 2026 Google Core Update” that never happened.

And guess what? This blatant fake news didn’t just land on page one of Google’s search results — Google’s own AI Overviews recommended it to users as an authoritative fact!

We’re living in an age where AI-generated content is flooding everything, and we all rely on Google every day to research and shape our SEO strategies. But this experiment is a wake-up call: how trustworthy is the top-ranking content you see on Google — even the answers AI itself gives you?

Today, let’s dig into this story and see what it teaches us — whether you run an overseas independent site in B2B or B2C.

1. A wild experiment born from an AI “hallucination”

The backstory is simple. Jon Goodey regularly uses AI to help him write his LinkedIn newsletter, and his workflow includes a human review step. One day, he spotted a serious “hallucination” — the AI confidently invented a completely fictional “March 2026 Google Core Update.”

Instead of deleting it, Jon got curious: what would happen if I just publish this? Would anyone even call it out as fake?

And so began an experiment on internet information spread and Google’s algorithms.

Neo’s take: In our daily independent site operations, a lot of us use ChatGPT or Claude to batch-generate blog posts. Jon’s story is a reminder that AI hallucinations are real and far more common than we’d like. If you don’t have a strict human-in-the-loop review process, those professional-sounding but wrong pieces of information can end up on your own site — and quietly destroy your brand trust.

2. Google itself vouching for fake news?

The results were stunning. Jon’s LinkedIn article didn’t get buried at all — searching “Google March update 2026” put it right on page one of Google’s results!

And here’s the kicker: Google’s own AI Overviews grabbed the fabricated information and presented it to users as “fact.”

Jon’s reaction: “It wasn’t buried on page three. It’s right there, visible to anyone searching for recent Google algorithm changes. Google’s own AI treated it as fact.”

The truth is, Google’s fact-checking has always been paper-thin. Search for certain black hat SEO tactics like “Google Stacking,” and Google will happily recommend these shady practices as legitimate strategies — which is dangerously misleading for owners and operators who don’t know any better.

Neo’s take: What does this mean for us? Google’s ranking algorithm and AI Overviews currently weigh “relevance” and “publishing platform authority” (LinkedIn carries a ton of weight) far more than “truthfulness.” That’s also why parasite SEO is still thriving. But flip it around: publishing quality content on high-authority platforms is still a fast track to rankings.

3. The SEO echo chamber: fake news becomes “real”

The story gets even more absurd.

Because “Google core update” carries a huge traffic halo, independent SEOs and tech sites spotted Jon’s article and pounced on it like sharks smelling blood.

Nobody bothered to verify anything — they just piled on. TechBytes, a tech site, not only covered the “fake update” but confidently invented hyper-technical details like:

• Gemini 4.0 Semantic Filter
• Zero Information Gain (a “classification system”)
• Discover 2.0 Engine

One fake article, amplified and polished inside the internet’s echo chamber, turned into a full-blown “fact” that everyone believed.

Neo’s take: This is textbook internet information pollution. When you’re doing competitor research or market analysis for your B2B or B2C independent site, never blindly trust whatever ranks at the top. A lot of so-called “industry consensus” is just mutual plagiarism. In the AI era, the ability to get first-hand data and unique insights is your real moat.

4. Why won’t Google fact-check?

At this point you might ask: Google is the world’s largest search engine — why doesn’t it just build in fact-checking?

Well, Google’s position has been pretty clear. News reports have noted that Kent Walker, Google’s president of global affairs, explicitly said Google refuses to comply with EU laws requiring fact-checking to be integrated into its ranking systems and algorithms.

Google argues that mandated fact-checking integration is “inappropriate and ineffective” for its services. Instead, it prefers relying on existing content moderation and features like Community Notes on YouTube.

In short, Google is an information retrieval tool. Its job is to find relevant content — the responsibility for separating truth from fiction is pushed onto the user.

Neo’s take: If Google won’t verify what’s true, how does it judge a website’s quality? The answer is still E-E-A-T (Experience, Expertise, Authoritativeness, Trust). Google can’t fact-check your content line by line, but it evaluates your brand reputation, author background, backlinks, and other signals to decide whether your site deserves trust. So building genuine brand trust matters more than obsessing over whether any single article is true or not.

5. Summary: the way forward for independent site sellers

This fake Google update story is like a mirror, showing us how fragile and absurd the AI search era really is. For everyone running an overseas independent site, here are the takeaways:

1. Watch out for AI hallucinations — keep humans in the loop: your content production workflow must include strict fact-checking and logic verification. Don’t let AI wreck your brand’s reputation.
2. Think independently and cross-verify everything: whether it’s an SEO tutorial or an industry report, don’t believe it just because it ranks on Google’s first page or came from an AI answer. Most people don’t verify — be one of the few who stay clear-eyed.
3. Respect domain authority: the fake news ranked partly because it rode on LinkedIn’s authority. Use high-authority platforms like Reddit, LinkedIn, and Quora strategically for your brand content.
4. Create content with real information gain: TechBytes made up the term “zero information gain,” but information gain itself is something Google genuinely cares about. Only real case studies and deep data that nobody else has will keep your independent site standing in the AI era.

In a world where AI churns out content endlessly, real, deep, practice-based experience is the rarest gold there is.
